What the thread found

• The EX-3 can be mounted on an aerial arm and flown successfully when equipped with a PRO 35 adapter, heavy cinema lenses, and sufficient ballast or mounting hardware to balance the weight.
• A weight cage is necessary for flying the EX-3 if the camera is used without substantial auxiliary equipment like PRO 35 adapters, full-size lenses, or sliding base plates.
• The camera's bottom surface is not flat, which causes movement and instability unless additional support structure is added underneath.
• Preston remote cables connected through the PRO 35 adapter can control the spinning mirror but cannot start or stop the EX-3 camera recording.
• An adapter cable is available that converts the Canon 8-pin broadcast lens connection to the Sony camera connector, potentially enabling Preston remote run-stop control through a Fuji lens control socket on the PRO 35 adapter.
• Lens gear adapters for the EX-3 are available for rent from equipment houses and can be purchased from cinema supply retailers or as screw-on versions from specialty manufacturers.
• Aftermarket baseplate systems exist that attach via screw mounts to address the flat-bottom issue and provide stable support for the camera.

Depends on

• The remote control workaround through Fuji lens control socket was untested by the discussion participants for actual start-stop functionality.
• One user did not attempt to verify whether the Preston cable solution would work with the PRO 35 setup.
• Specific equipment availability and pricing information is incomplete or potentially outdated from 2009.
• The discussion mentions both EX-1 and EX-3 interchangeably without always clarifying which model specific solutions apply to.
